PBR Ultra-Light Hard Anodized Aluminum Sprocket 4586 - 520
Manufacturer reference: 4586 42 LD
Designed for riders looking to lighten their transmission without sacrificing strength, this PBR sprocket made from hard anodized aluminum combines lightness and durability. Its machining and surface treatment provide good resistance to corrosion and abrasion while reducing friction between the chain and the sprocket.
- Material: hard anodized aluminum, stainless steel finish
- Number of teeth: 42
- Chain pitch: 520 (standard)
- Type: standard, design based on PBR racing experience
Ideal for installation on roadsters or sport machines using a 520 pitch, it allows for a slight modification of the gearing while maintaining a smooth chain engagement. The anodized surface limits wear and facilitates maintenance after road outings or more intense sessions.
Application examples (to be verified according to year and version): BMW S 1000 RR ABS (2014, 2016, 2018).
Before installation, check the exact compatibility with your original setup (bolt pattern, bolt spacing, and thickness). For riders who want a high-performance, lightweight, and durable sprocket, this PBR reference is a reliable option for the transmission.
